Bindi and Robert Honor Their Dad by Celebrating Steve Irwin Day at the Australia Zoo

The late Crocodile Hunter’s family, including wife Terri and children Bindi and Robert, were at the Australia Zoo Tuesday to celebrate Steve Irwin Day alongside some of his favorite reptiles.

Clad in khakis, honoring Steve’s signature look, the family educated spectators about reptiles. Bindi, 18, even fed a giant croc while 12-year-old Robert, who looks like the spitting image of his father, held a young reptile in front of an audience at the zoo.

Bindi also honored her father with an Instagram post that shows Steve smiling and holding his young daughter as she points.

“Encouraging everyone to wear a touch of khaki on this amazing day to remember all that Dad did for our world, inspiring us all to love wildlife and wild places. Thank you,” she captioned the sweet snap.

Later in the day, Bindi shared three photos on Twitter of her late father wearing his khaki uniform. “Khaki and the happiest memories. #SteveIrwinDay,” she tweeted.

The animal activist died Sept. 4, 2006, following the attack of a stingray.

“Steve Irwin Day is such an incredible event that we hold each year together in honour of Steve, celebrating everything he was so passionate about – family, conservation and having fun,” Terri told the Sunshine Coast Daily. “He touched the lives of so many people and his important message of conservation is something everyone can be passionate about.”
